Description

Technical Field

[0001] This utility model relates to the field of open-pit mine blasting hole inclination measurement and correction technology, specifically to a rapid inclination measurement and correction device for open-pit mine blasting holes. Background Technology

[0002] Borehole tilt can lead to uneven charge distribution, affecting blasting fragmentation and block size distribution. Real-time monitoring of borehole tilt and azimuth deviations using inclinometer technology (such as the JDT3 gyroscope) allows for optimized charge design, ensuring effective energy release during blasting. Borehole tilt can also cause deviations in blasting vibration direction, exacerbating slope rock damage. Combining inclinometers with GNSS displacement monitoring can identify potential slip surfaces and adjust borehole trajectory using correction techniques, reducing the impact of blasting on slope stability.

[0003] Conventional rapid inclination and correction devices for open-pit mine blast holes mostly employ a single, fixed structure. When faced with blast holes of varying depths and angles, they struggle to achieve flexible adjustments and precise measurements. The relatively fixed installation positions of their detection components prevent multi-dimensional adjustments based on the complexities of the actual blast hole, limiting the accuracy and comprehensiveness of the measurement data. Furthermore, their poor stability during movement and positioning makes them susceptible to external interference, impacting the efficiency and quality of inclination and correction work. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid inclination measurement and correction device for blasting holes in open-pit mines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid inclination and correction device for blasting holes in open-pit mines, comprising a device frame and an adjustment frame. A movable seat component is connected and installed on the front side of the device frame. The adjustment frame is connected to the middle of the side of the movable seat component away from the device frame, and a detection component is connected and installed on the side of the adjustment frame away from the movable seat component. The adjustment frame includes a damping hinge, a fastening bolt, a fixing seat, and a docking seat. A fastening bolt is horizontally installed at the axis of the damping hinge, and a fixing seat is provided at the end of the damping hinge near the movable seat component, and a docking seat is provided at the end of the damping hinge away from the fixing seat.

[0006] Furthermore, the device frame includes a stabilizing support, an adjusting guide rail, a supporting corner plate, and fixing holes. The adjusting guide rail is symmetrically and vertically installed on the side of the stabilizing support near the moving seat component, and the supporting corner plate is symmetrically arranged on the lower end of the side of the stabilizing support away from the adjusting guide rail. In addition, holes for bolt installation are provided at the four opposite corners of the lower end of the stabilizing support.

[0007] Furthermore, the stabilizing support adopts an inverted "T" shaped structure, and the stabilizing support and the supporting corner plate are welded together.

[0008] Furthermore, the movable seat component includes a ratchet turntable, a shock absorber frame, a damping slider, and a limit bolt. The shock absorber frame is connected and installed on the side of the ratchet turntable close to the adjustment frame component, and the damping slider is symmetrically arranged on the left and right sides of the side of the ratchet turntable away from the shock absorber frame. Moreover, the upper and lower ends of the damping slider are both horizontally threaded with limit bolts.

[0009] Furthermore, the damping slider and the ratchet turntable are fixedly connected, and the damping slider and the adjusting guide rail are interconnected by a slotted embedded structure.

[0010] Furthermore, the four diagonal corners of the connection between the ratchet turntable and the shock absorber are provided with holes for bolt installation, and the end of the shock absorber away from the ratchet turntable is combined and connected with the side of the fixed seat away from the damping hinge.

[0011] Furthermore, the detection component includes a displacement sensor, a mounting base, a correction detector, and a protective shell. The displacement sensor is provided with a mounting base on the side near the adjustment structure component, and a correction detector is installed at the bottom of the displacement sensor. Moreover, a protective shell is installed on the outside of the correction detector.

[0012] Furthermore, the displacement sensor is fixedly connected to the mounting base, and the side of the mounting base away from the displacement sensor is connected to the side of the mating base away from the damping hinge.

[0013] This utility model provides a rapid inclination measurement and correction device for blasting holes in open-pit mines, which has the following beneficial effects: This invention features an adjustable frame on one side of the detection component. The damping hinge within this frame allows for flexible adjustment of the detection component's vertical tilt angle within a certain range. This enables the detection component to more precisely conform to the inner wall of the blast hole, resulting in more accurate tilt data. Simultaneously, the fastening bolt design ensures structural stability after the damping hinge adjustment, preventing angular deviations caused by vibration or external forces during detection, thus improving the accuracy and reliability of the inclination measurement. Furthermore, the damping hinge is made of high-strength alloy material, possessing excellent wear resistance and fatigue resistance, maintaining stable performance even with frequent adjustments. The fastening bolt, through a precise thread design, tightly engages with the damping hinge, ensuring a secure lock after the detection component's angle is adjusted, preventing loosening from affecting measurement accuracy. The mounting base, fixed seat, and docking seat all undergo special surface treatment to enhance the connection strength and stability with adjacent components, reducing the risk of loosening due to vibration or external impact. The displacement sensor uses imported high-precision sensor elements, and its measurement range and accuracy can meet the stringent requirements of open-pit mine blasting hole inclination measurement. The mounting base adopts an integrated molding process, tightly combined with the displacement sensor, effectively reducing measurement errors caused by assembly gaps. The microprocessor built into the correction detector has powerful data processing capabilities, enabling it to analyze and process the data collected by the displacement sensor in real time and quickly issue accurate correction commands. The protective shell is not only made of high-strength, corrosion-resistant materials, but also has an internal shock-absorbing and buffering structure, further improving the impact resistance of the detection components in harsh environments and ensuring the long-term stable operation of the device.

[0014] 2. This utility model, through the structural design of its device components, includes an inverted "T"-shaped stable support with welded connections to the support angle plates, providing a stable foundation for the entire device. Simultaneously, the fixing holes at the four diagonal points at the lower end of the stable support facilitate the secure fixing of the device to the work platform with bolts, preventing measurement accuracy from being affected by device movement during inclination and correction. The slotted embedded structure of the damping slider in the adjusting guide rail and moving seat component allows the moving seat component to move smoothly and steadily along the adjusting guide rail, thereby driving the detection component to achieve precise vertical positioning and ensuring accurate detection. The device can accurately measure the location of blast holes, improving the flexibility and accuracy of measurements. Furthermore, the unique ratchet turntable design in the moving seat component not only allows for full rotation of the detection component in the horizontal plane, facilitating measurements of blast holes from different angles, but also, through the combination and connection of the damping frame and the fixed seat of the adjusting frame, effectively reduces the impact of vibrations generated during blasting on the detection component, ensuring the stability of the measurement data. Simultaneously, the limit bolts with horizontal threads at both ends of the damping slider precisely limit the movement range of the moving seat component, preventing it from exceeding the predetermined stroke, further enhancing the safety and reliability of the device.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 5As shown, a rapid inclination and correction device for blasting holes in open-pit mines includes a device frame 1 and an adjusting frame 3. A movable base component 2 is connected and installed on the front side of the device frame 1. The adjusting frame 3 is connected to the middle of the side of the movable base component 2 away from the device frame 1, and a detection component 4 is connected and installed on the side of the adjusting frame 3 away from the movable base component 2. The adjusting frame 3 includes a damping hinge 301, a fastening bolt 302, a fixing seat 303, and a docking seat 304. The fastening bolt 302 is horizontally installed at the axis of the damping hinge 301, and the fixing seat 303 is provided at the end of the damping hinge 301 near the movable base component 2. The docking seat 304 is provided at the end of the damping hinge 301 away from the fixing seat 303. The detection component 4 includes a displacement sensor 401, a mounting base 402, a correction detector 403, and a protective device. The housing 404 has a mounting base 402 on the side of the displacement sensor 401 near the adjustment frame component 3, and a correction detector 403 is installed at the bottom of the displacement sensor 401. The correction detector 403 is also covered by a protective housing 404. The displacement sensor 401 and the mounting base 402 are fixedly connected. The side of the mounting base 402 away from the displacement sensor 401 is connected to the side of the docking seat 304 away from the damping hinge 301. The damping hinge 301 in the adjustment frame component 3 can flexibly adjust the up-and-down folding angle of the detection component 4 within a certain angle range in the vertical direction, so that the detection component 4 can more accurately fit the inner wall of the blast hole, thereby obtaining more accurate tilt data. At the same time, the design of the fastening bolt 302 ensures the structural stability of the damping hinge 301 after adjustment.

[0019] like Figures 1 to 5As shown, the device frame component 1 includes a stabilizing support 101, an adjusting guide rail 102, a support angle plate 103, and fixing holes 104. The adjusting guide rail 102 is symmetrically and vertically mounted on the side of the stabilizing support 101 closest to the moving seat component 2. The support angle plate 103 is symmetrically arranged on the lower end of the side of the stabilizing support 101 furthest from the adjusting guide rail 102. Holes for bolt installation are provided at the four opposite corners of the lower end of the stabilizing support 101. The stabilizing support 101 adopts an inverted "T" shape structure, and the stabilizing support 101 and the support angle plate 103 are welded together. The movable seat component 2 includes a ratchet turntable 201, a shock absorber frame 202, a damping slider 203, and a limit bolt 204. The shock absorber frame 202 is connected and installed on the side of the ratchet turntable 201 closest to the adjusting frame component 3, and the damping sliders 203 are symmetrically arranged on the side of the ratchet turntable 201 away from the shock absorber frame 202. Limit bolts 204 are horizontally threaded onto both the upper and lower ends of the damping sliders 203. The damping sliders 203 and the ratchet turntable 201 are fixedly connected, and the damping sliders 203 and the adjusting guide rail 102 are interconnected using a slotted embedded structure. The shock absorber 202 has four diagonal holes for bolt installation at its joints. The end of the shock absorber 202 away from the ratchet turntable 201 is connected to the side of the fixed seat 303 away from the damping hinge 301. The stabilizing support 101, with its inverted "T" shape and the stable support plate 103, provides a solid foundation for the entire device. The slotted fit between the adjusting guide rail 102 and the damping slider 203 ensures that the moving seat component 2 can move smoothly along a predetermined path. This design not only improves measurement accuracy but also enhances the detection... Component 4 can quickly and accurately position itself at the designated measurement location of the blast hole. The 360-degree rotation function of the ratchet turntable 201 greatly facilitates the inspection work, allowing the inspection component 4 to perform detailed measurements of the blast hole from various angles. The shock absorber 202 effectively isolates the vibration generated during the blasting process, protecting the inspection component 4 from damage and ensuring the stability of the measurement data. The limit bolt 204 provides precise limitation on the movement range of the moving seat component 2, preventing safety accidents that may be caused by excessive movement and further enhancing the safety of the device.

[0020] In summary, as Figures 1 to 5 As shown, when using this open-pit mine blasting hole rapid inclination and correction device, the device is first installed on the work platform through the fixing hole 104 at the lower end of the stabilizing support 101 using bolts to ensure that the device remains stable during the inclination and correction process. Next, based on the approximate location of the blast hole, the position of the damping slider 203 on the adjusting guide rail 102 is adjusted so that the moving seat component 2 drives the detection component 4 to perform preliminary positioning in the vertical direction, ensuring that the detection component 4 can approach the blast hole to be measured. Then, using the 360-degree rotation function of the ratchet turntable 201, the angle of the detection component 4 in the horizontal plane is adjusted so that it can be aligned with the blast hole from the best angle. During the adjustment process, the shock absorber 202 can effectively reduce the impact of blasting vibration on the detection component 4 and ensure the stability of the measurement data. Once the detection component 4 is aligned with the blast hole, it is flexibly adjusted within a certain angle range in the vertical direction via the damping hinge 301, allowing the detection component 4 to fit more precisely against the inner wall of the blast hole. At this time, the displacement sensor 401 starts working, collecting the tilt data of the blast hole in real time and transmitting it to the correction detector 403. The microprocessor built into the correction detector 403 analyzes and processes the collected data and quickly issues accurate correction commands. If the blast hole is detected to be tilted, the correction detector 403 will adjust the drilling trajectory according to the degree and direction of the tilt through the corresponding control mechanism to ensure the safety and accuracy of subsequent blasting operations. Throughout the entire inclination measurement and correction process, the protective shell 404 not only protects the precision components inside the detection component 4 from the influence of harsh environments, but also further improves the impact resistance of the detection component 4 through the internal shock-absorbing and buffering structure. At the same time, the setting of the limit bolt 204 ensures that the movement range of the moving seat component 2 during the adjustment process will not exceed the predetermined stroke, further improving the safety and reliability of the device. Through this operating procedure, the open-pit mine blast hole rapid inclination measurement and correction device can efficiently and accurately complete the inclination measurement and correction work of the blast hole.
